1. A regular silt fence may be used where:

a. No other practice is feasible or economical.

b. There is no concentration of water in a channel or other drainage-way above the barrier.

c. Erosion will occur in the form of sheet and rill erosion.

d. Protection of a property line or limits of grading is required.

e. 100 feet of silt fence will collect the runoff from an area of ¼ acre or less, and the maximum gradient is 2:1 or less.

2. A super silt fence may be used where:

a. Sensitive areas (wetlands, woods, streams, etc.) are adjacent to the project location.

b. Structures, such as residential homes or commercial buildings, are down slope and in close proximity to the disturbed areas.

c. The project location is prone to heavy winds and drifting snow.

d. The disturbance is anticipated on lasting for a long duration, over one year.

SECTION 01565 - 3

e. Sediment traps cannot be built due to land availability.

f. Indicated by the Engineer or regulatory agency.

D. Materials

4. See Erosion and Sediment Control detail sheets.

2.2 TEMPORARY DITCH STONE CHECK DAMS

A. Definition

1. A “temporary” barrier with a life expectancy of the project, installed across a ditch or swale.

B. Purpose

1. The purpose of a temporary ditch stone check dam is to detain small amounts of sediment and to slow the water flow to prevent erosion before vegetation or grass has taken root.

C. Construction Specifications.

1. The ditch stone check dams shall consist of rock, fieldstone, or quarry stone 3” to 6” size.

2. The ditch stone check dams shall be 6” minimum and 2’ maximum in depth and 4’0” minimum in length, dumped into bottom of ditch line.

3. An inspection shall be in accordance with Paragraph 3.4 of this Section and sediment should also be removed to insure capacity when sediment reaches one-half height of barrier.

4. The ditch stone check dams will be spaced as follows:

(Calculate by formula) L = Length in feet S = Rise over run – multiply by 100 L = 160/S (maximum 150’)

5. The ditch stone check dams shall not be removed completely but shall be used in the construction of rock-lined ditch. The rock shall supplement the rock required to install the rock-lined ditch.

6. See Construction Drawings for detail sheets.

SECTION 01565 - 5

2.3 TEMPORARY SEDIMENT TRAPS

A. Definition

1. A temporary basin formed by excavation and/or embankment to intercept sediment-laden runoff to trap or retain sediment prior to re-entering the waterway.

B. Purpose

1. To intercept sediment runoff and trap the sediment in order to protect drainage ways, properties and rights-of-ways from sedimentation.

C. Construction Specifications.

1. Size of temporary sedimentation basin must be by calculation and submittal by the Owner to the Department of Environmental Protection.

2. Area under embankment shall be cleared, grubbed, and stripped of any vegetation and root mat. The pool area shall be cleared.

3. The fill material for the embankment shall be free of roots or other woody vegetation as well as oversized stones, rocks, organic material or other objectionable material. The embankment shall be compacted by traversing with equipment while it is being constructed.

4. Sediment shall be removed and trap restored to its original dimensions when the sediment has accumulated to ½ wet volume of the trap.

Removed sediment shall be deposited in a suitable area and in such a manner that it will not erode.

5. The structure shall be inspected at least once every seven (7) calendar days and within 24 hours of any storm event of 0.5 inches or greater of rain per 24-hour period. See attached example inspection form.

6. Construction operations shall be carried out in such a manner that erosion and water pollution are minimized.

7. The structure shall be removed and area stabilized when the remaining drainage area has been properly stabilized.

8. All cut and fill slopes shall be 2:1 or flatter.

9. All pipe joints shall be watertight.

SECTION 01565 - 6

10. Fill material around the pipe spillway shall be hand compacted in 4-inch layers. A minimum of two feet of hand compacted backfill shall be placed over the pipe spillway before crossing it with construction equipment.

11. Outlet crest elevation shall be, at least, below the top of the embankment, except for pipe or stone outlets. This shall be at least 1.5 feet for pipe outlets and 1 ft. for stone outlets.

12. The crushed stone used in the outlet shall meet AASHTO designation M43, Size No. 2 or 24, or it’s equivalent. Gravel meeting the above gradation may be used if crushed stone is not available. Crusher run is not acceptable.

13. Sediment traps and basins must be capable of safely passing the peak discharge from a 25 year, 24-hour storm event with one foot of freeboard after settling.

2.4 PIPE LAYING ALONG STREAM

A. Special precautions against soil erosion must be taken when laying pipelines along stream. These are listed below:

1. Where the stream bank has been disturbed and is not to be protected with rock fill, a nylon blanket netting as manufactured by North American Green, Inc., P-300 or equal, shall be installed from the bottom of the stream to the high water mark to hold the mulch in place.

2. Mulch and netting shall be installed within twenty-four (24) hours of completion of the pipe installation on that section of the stream.

3. All grading should be limited to the minimum necessary to install the crossing.

4. Grading of the approaches shall be done by backblading or other similar methods so as to keep both soil and equipment out of the stream.

5. Cofferdam or other approved diversionary technique included in the construction drawings or specifications should be used wherever possible to divert flow to one part of the stream while construction work is being performed on another part.

6. All sediment-laden water pumped from ditch lines and cofferdams should be filtered and discharged to a stable area.

7. Equipment shall not enter a stream unnecessarily. Most work can be done from the bank or inside the cofferdam area.

SECTION 01565 - 7

8. Spoil shall be stored and/or disposed of outside the limits of normal high water and in such a way that it will not re-enter the stream.

9. Green concrete is toxic to aquatic life and should be kept out of contact with the flowing stream for seventy-two (72) hours. Cofferdams must be used if green concrete is to be placed in the stream.

10. Surface water runoff should be diverted away from approaches.

11. Approaches shall be reshaped, fertilized, limed, seeded and mulched immediately upon completion of construction activities and/or otherwise adequately stabilized.

12. Material for backfilling the ditch in the stream shall be able to withstand normal stream flows without excessive erosion.

13. Where the Contractor intends to continuously cross a steam, creek, or river with equipment and vehicular traffic, the streambed shall be protected as required by the WV Department of Environmental Protection. The Contractor shall submit to the Owner a plan for temporary stream crossing, which would be subject to WV DEP approval.

2.5 COFFERDAMS

A. Cofferdams are structures to enclose and divert flow around a portion of a stream so the enclosed area can be dewatered. Their primary functions are to make in stream construction work easier while minimizing pollution from the construction work. They can be constructed with sand bags, concrete traffic barriers, or other non-erodible materials.
